BOTTLE-TAP.

SPECIFICATION formingpart of Letters Patent No. 757,794, dated April 19, 1904.

Application tiled September 2, 1903. Serial No. 171,612. (No model.)

To all whom it may concern:

Beit known that I, EDWIN IALKER, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Bottle-Taps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to bottle-taps adapted to withdraw eifervescent liquids from bottles without removing' the cork therefrom whereby the contents of such bottles can be withdrawn at such intervals as may be desired without any material portion of the gases therein escaping, so that the liquid remaining in the bottle will not deteriorate or spoil.

Iaccomplish the desired result by constructing my improved bottle-tap of a hollow stem or screw bored out its entire length, but having its bore reduced for a short distance at its inlet end, and on the outlet end of this stem there is a head provided with a valve-seat and valve and with cross-arms for screwing the stem through the cork, one of which arms is hollow, with the opening therein communicating with the opening in the head above the valve-seat therein, and in this head there is a valve adapted to close down upon the valveseat therein. Extending downward from the valve there lis a rod which iits the reduced portion of the opening in the stem or screw and extends slightly beyond the inlet end thereof and is tapered to a point, said reduced portion of the stem and the tapered end of the rod forming together a point for the stem or screw, so that it can be readily screwed through a bottle-cork, and when the valve is raised from the seat the 'tapered outer end of the rod is withdrawn thereby from the reduced portion of the inlet end of the stem or screw, so as to allow the fluid in the bottle to flow upwardly therethrough and around the rod in the larger portion of the bore in the stem.

The features of my invention are hereinafter more fully set forth and described, and illustrated in the accompanying drawings, in which- Figure l shows my improved bottle-tapl'in elevation. Fig. 2 shows a vertical section thereof. 'Fig 3 shows an enlarged vertical section of the lower end of the stem or screw and ofthe rod therein.

In the drawings, A is a screw upon which there is a head B, provided with a valve-seat therein. On this head B there are lateral arms D and D, the arm D being preferably inclined upward and bored out, so as to have an opening Z therein, which communicates with the opening in the head B above the valveseat I). rlhe head B is bored out and screwthreaded above the Valve-seat and is provided with a valve E, operating therein, provided with packing e, adapted to tit down upon the valve-seat b. The valve E is also provided with athumb-piece E', by means Whereof the valveE can be operated in the head B. Below the valve-seat the stem A is bored out, as at A, down to near the extreme point a thereof, and at a the bore is reduced, as is clearly shown in Figs. 2 and 3, so that above the point a the bore A" is considerably larger. The lower end a is also pointed down to the reduced opening at the extreme end thereof. To the valve E there is attached a rod F, which extends through the bore A and through the contracted portion thereof at a and is of such diameter that it will pass freely through the same, and yet tit the inlet-opening sufficiently close to prevent particles of cork from entering or clogging the same, and the outer end f of the rod is pointed, so that when the valve E is closed the pointed end f of the rod 1-F forms a continuation of the pointed end a of the screw or stem A, as shown in all of the figures, so that when the valve is closed the stem is provided with a complete point for penetrating the bottle-cork; but when the Valve E is opened it withdraws the pointed end f of the rod F from the contracted portion of the bore A in the stem or screw A and back into the enlarged portion thereof, so that liquid can flow therethrough freely.

From the foregoing description it is bclieved the operation of my improved bottle- TOO tap is so obvious that further description thereof is unnecessary.

Therefore, having fully described my invention, so as to enable others to construct and use the same, whatI claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination in a bottle-tap, of a hollow stem having the inlet end of the opening therein contracted, a valve for closing the outlet of the opening in the stem, and a rod operated by said valve extending through the opening in the stem and the contracted inlet portion thereof, and adapted to be withdrawn from ythe contracted portion thereof by the operation of the valve, substantially as set forth.

2. The combination in a bottle-tap, of a stem having a central opening therein contracted at its inlet end, a head ,on the outlet end of said stem, a valve-seat in said head, la valve in said head operating on said valveseat, a discharge-opening in said head above the valve is closed a sucient distance to .form

a portion of the point of the stem, substantially as set forth.

In testimony whereof I afx my signature in presence of two witnesses.

EDWIN WALKER.
